Study uses satellite data to add to growing evidence that nighttime light exposure raises risk of breast cancer, with the strongest link among young women.
Color-changing cells in an Atlantic squid’s skin contain light-sensitive pigments.
We're used to thinking of our eyes detecting light as the foundation of our visual system. But what's going on in other cells throughout the body that can detect light, too?

All parents have probably struggled to get their kids to sleep at some point. This is even more difficult when a child has ADHD.
Children with ADHD are much more likely than other kids to struggle getting to sleep, and staying asleep. Up to 73% of Australian parents report their child with ADHD has problems sleeping.
Micro changes have macro results.

New research suggests our gut microbes have their own circadian rhythms that in turn influence our organ functions. Is this an explanation for how disrupting our daily patterns can cause health problems?

Gaining a better sense of what genes are involved in regulating circadian clocks could put us on a path to find better treatments and therapies to help people adjust to time shifts.

Is electricity making us sleep less? A new study on sleep in preindustrial societies suggests the answer is no. But it misses a big point: people in preindustrial societies spend more time in darkness than we do.

How does one prove that shift work causes breast cancer, as the authors of the new study claim? A cancer epidemiologist explains how scientists weigh evidence to figure out what causes cancer.
Turn that off.

Today, most of us get too little light during the day and too much at night for our circadian rhythm to function at its best.
Light from electronic devices can alter the quality of sleep our quality.
While many of these devices, especially e-readers, seem harmless enough, the light they emit may affect our sleep patterns and leave us feeling tired the next day.
Time spent checking the clock when you can’t sleep may be feeding your insomnia.
We all have a poor night’s sleep from time to time: those nights when you lie awake for hours trying desperately to go to sleep but can’t stop worrying about tomorrow. Or when you repeatedly wake up throughout…
Athletes will need to watch their sleeping habits if they want to finish first.
